Solution Overview

Problem

Existing tensors for bracing vertical structures to the ground are difficult to assemble and disassemble, especially when the attachment point is inaccessible to the operator due to height limitations.

Innovation Solution

A tensor design with an elongate body and a head featuring an oblique groove and pivotable locking means that allows attachment to a horizontal bolt from the ground, enabling easy assembly and disassembly by adjusting the inclination angle to lock the bolt in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the tensor is fixed to the vertical structure at a height greater than 2m, then the bracing effectiveness is improved, but the assembly becomes difficult or impossible for an operator to perform from the ground

Engineering Contradiction:

Improvebracing effectivenessVSAvoidassembly accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The tensor incorporates a dynamic locking mechanism with a groove and pivotable locking means that changes state based on the inclination angle. When the tensor is raised at a shallow angle, the locking means allows the horizontal bolt to move freely along the groove. When tilted to the locking angle or greater, the locking means automatically engages to retain the bolt, providing dynamic adaptability that enables ground-level assembly while maintaining high-position bracing effectiveness

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The invention changes the parameter of inclination angle to control the assembly process. By raising the tensor at an angle smaller than the locking angle, the operator can easily hook the head onto the horizontal bolt from the ground. Then by tilting to increase the inclination angle to the locking angle or greater, the locking means automatically engages. This parameter change enables the tensor to be assembled from the ground while maintaining the ability to brace at heights greater than 2m

Inventive Principle:

Principle #35Parameter changes

2Strength

If the tensor uses a traditional fixed attachment method, then the connection strength is improved, but the time required for assembly and disassembly increases

Engineering Contradiction:

Improveconnection strengthVSAvoidassembly time

Core Design Contradiction:

StrengthVSLoss of time

Solution Approach 1:

The locking mechanism dynamically responds to the inclination angle change. When the tensor is tilted to the locking angle or greater, the locking means automatically engages to retain the horizontal bolt, providing strong connection without requiring manual intervention. For disassembly, the operator simply lowers the inclination angle below the locking angle, and the locking means automatically releases, enabling quick assembly and disassembly while maintaining connection strength when locked

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The locking mechanism is self-activating based on the inclination angle. When the tensor is tilted to the locking angle or greater during assembly, the locking means automatically engages to retain the horizontal bolt without requiring manual operation. Similarly, when lowered below the locking angle, it automatically releases. This self-service mechanism eliminates the need for additional locking operations, reducing assembly time while maintaining connection strength

Inventive Principle:

Principle #25Self-service
